public JDOQLQueryFactory getJDOQLQueryFactory()

Returns the JDOQLQueryFactory bound to this FOStorePMF.

Returns:

JDOQLQueryFactory

newQueryTree

public QueryTree newQueryTree()

Returns a new QueryTree instance. This instance allows to specify a query with an API (see QueryTree and ExpressionFactory) rather than as JDOQL strings. To run you create a query object from the QueryTree (see PersistenceManager.newQuery(Object compiled)) and call the execute method on the Query object.

Returns:

new QueryTree instance.

createPersistenceManager

protected javax.jdo.PersistenceManager createPersistenceManager(java.lang.String userid,
                                                    java.lang.String password)

Create a new instance of PersistenceManager with the specific user name and password.

Specified by:

createPersistenceManager in class PersistenceManagerFactoryImpl

Parameters:

userid - the user name

password - the password

Returns:

the Persistencemanager

See Also:

PersistenceManagerFactoryImpl.createPersistenceManager(String userid, String password)

close

public void close()

Close this PersistenceManagerFactory. Check for JDOPermission("closePersistenceManagerFactory") and if not authorized, throw SecurityException.

If the authorization check succeeds, check to see that all PersistenceManager instances obtained from this PersistenceManagerFactory have no active transactions. If any PersistenceManager instances have an active transaction, throw a JDOUserException, with one nested JDOUserException for each PersistenceManager with an active Transaction.

If there are no active transactions, then close all PersistenceManager instances obtained from this PersistenceManagerFactory, mark this PersistenceManagerFactory as closed, disallow getPersistenceManager methods, and allow all other get methods. If a set method or getPersistenceManager method is called after close, then JDOUserException is thrown.

Specified by:

close in interface javax.jdo.PersistenceManagerFactory

Overrides:

close in class PersistenceManagerFactoryImpl

close

public boolean close(boolean force)

Closes the database unless there are any active store managers.

Parameters:

force - If true, forces the database to close anyway, regardless of whether or not any store managers are still active.
